MARSHIEALLGRV-BEATING MAGHIINE.

Application filed July 13,

T all whom it may concern.

Be it known that 1. Fauna M. CHASE, a citizen of the United States,residing at Springfield, in the county of Hampden and State ofldassachusetts, have invented a new and useful Marshmallow-BeatingMachine, of which the following is a specification.

This invention relates to a machine for mixing and beating marshmallowpaste or other similar food materials.

It is the general object of my invention to improve the construction ofsuch machines as heretofore known, to the end that they may be moresubstantially fabricated, less liable to leakage and other defects whenin use, and cleaner and more convenient in operation and discharge.

VVith-these objects in view, important features of my invention relateto the manner of joining the several parts together and particularly tothe construction and mounting of the cover which closes the feed Opening of the machine.

My invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

A preferred form of the invention is shown in the drawings in which Fig.1 is a rear elevation of my improved machine; r

Fig. 2 is an end elevation looking in the direction of the arrow 2 inFig. 1; I

Fig. 3 is a detail sectional view taken along the line S-3 in Fig. 1; v

Fig. etis an enlarged sectional detail taken along the lines 4-l in Fig.2; and

Fig. 5 is an enlarged sectional detail looking in the direction of thearrow 5 in Fig. 1.

Referring to the drawings, my improved beating machine comprises a standor frame upon which is supported a barrel or mixing chamber having headsor end members 11, an inner cylindrical wall or shell 12, and an outercasing 13.

The walls 12 and 13 are spaced apart as shown in Fig. 1 to provide awater jacket for which water may be admitted through an inlet pipe 14and may be discharged through an outlet pipe 15. Heating pipes 16 permitcirculation of steam through the water between the walls 12 and 13, tomaintain the water in the jacket at any desired temperature.

1923. Serial No. 651,275.

In order to provide an exceedingly durable barrel or casing, Ipreferably join the inner and outer walls 12 and 18 and the end members11 as indicated in Fig. l. The inner wall 12 and outer wall 13 areprovided with out-turned flanges 17 and 18 and the adjacent heads or endmembers 11 are bent around the outer edges of the flanges 17 and 18 andare then bent inward to form clamping or binding flanges 19. Bolts 20extend through the frame 10, an end member 11 and the flanges 17, 18 and19, bindingthe several parts together and firmly securing them in theframe. After the parts are thus secured, the joints are carefully filledin with solder as indicated at 21 and 22 and a'strong, rigid, andwatertight construction is thus obtained.

hen beating marshmallow paste, a considerable amount of air is absorbedby the paste and it is necessary to provide a free connection to theatmosphere while at the same. time preventing the escape of paste duringthe beating operation. For this pur- .;pose I have provided the improvedcover construction indicated in Fig. 2 and shown in detail in Fig. 5.

My improved cover 25 is pivoted on a rod 26 secured to outwardlyextending portions of the end frames of the machine. The cover ispreferably of hollow sheet metal construction and a partial sectionthereof is clearly shown in Fig. 5. One end wall 26 of the cover isspaced from the out-turned flanges 2? and 28 of the cylinder walls 12and 13 and these out-turned flanges terminate somewhat below the pivotof the cover 25, thus providing a continuous open air passage 29 whenthe cover is closed.

The inner surface 25 the corer is extended in the direction of rotationpast the lower end of the air passage 29 and effectually prevents anyescape of paste through the air passage, as the direction of rotation ofthe beater carries the paste steadily onward and prevents the reversemovement necessary in order to enter the air passage.

Chains 30 are each secured at one end to the cover 25 and at theopposite end to an end frame of the machine and limit outward andrearward movement of the cover. These chains are of flat linlrconstruction, such that they do not bend readily in a lateral direction,and consequently there is no possibility of their being caught under thecover as it is closed.

A gate provided at one end of the beater and this gate may be raisedwhen desired by means of a handle 33 pivoted to the gate and connectedby a link 3i to a fixed pivot A pair of nuts or clamping devices 36 areprovided for securing the cover in closed position.

The interior of the beater is provided with the usual fixed arms 37 andmovable beater blades (Fig. 1), the blades being carried by a circular'l'rame rotatably mount- Gil in the barrel and connected to a driveshaft 39 provided with tight and loose pulleys l0 and +11. Accidentshave been heretoiore caused by starting the beater while the operatorwas engaged in removing the previous charge of paste therefrom. In orderto pre ent accidental shifting of the drive belt from the loose pulley nto the tight pulley l0, I provide a belt shifter 42 mounted to slide ona fixed rod l3 and provided with a latch adapted to positively lock thebelt shipper in either of its operative positions. he rod 43 is providedwith two notches elf) which receive the latch 44: and in which the latchis normally maintained by the weight of the handle portion thereof.Consequently the belt cannot be shifted to the tight pulley until thehandle of the latch at has been grasped and intentionally raised torelease the latch.

Having thus described my invention, the operation thereof will bereadily apparent. Attention is called to the convenience in operationdue to the improved construction of the cover lVhen this is raised asindicated in dotted lines in Fig. 2, it swings directly away from theoperator, leaving the entire front of the machine unobstructed.Furthermore, the two sides of the air passage 2) between the cover andthe frame are then widely separated, permitting thorough cleaning of alparts of the machine.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed otherwise than as setforth in the claims, but what I claim is 1. In a marshmallow beater, acasing having end members and inner and outer cylindrical walls of sheetmetal tirmly sccured together, said walls being spaced apart and havingout-turned flanges and said end members being folded it said out-turnedflanges to prevent 'rclat e displacement of said parts.

52. In a marshmallow beater, a frame, a ca -ing having end members andinner and outer cylindrical walls of sheet metal, and means to securesaid parts lirml together, said cylindrical walls being spaced apart andhaving adjacent out-turned flanges, said end members extending beyondand adjacent said end flanges and being reversclv bent inward aroundsaid flanges, and said securing means extending through said outturnedflanges, said enclosing end member and said frame to bind all of saidparts fiimly together.

3. In a marshmallow beater, a casing having an upper 't'eed openingtherein, and a, cover for said opening hinged at one side thereof, saidcover and casing being spaced apart at one side thereof to provide anair passage and the inner surface of said cover being extended beyondthe inner end of said passage.

I. In a marshmallow heater, a casing having outwardly extended wallportions torus ing an upper feed opening, and a cover for said openingpivoted beyond the outer end of said wall portions, said cover having aninwardly extending portion spaced from said wall portion at one side toform an air passage and said cover having also an inner surfaceextending beyond the inner end of said passage to prevent entrance oithe material in said heater to said passage.

In testimony whcreol I have hereunto aflixed my signature.
